NiSi NIR-UV395-49 49mm Round UV395 SMC Filter

The NiSi Round UV395 SMC Filter in 49mm brings premium optical quality to lens protection. Unlike entry-level UV filters that cut off around 370nm, this filter blocks ultraviolet light up to 395nm, providing more effective reduction of UV-induced haze and the subtle blue-purple color casts that can affect images shot outdoors or at altitude. The filter is built with Japanese optical glass that maintains edge-to-edge sharpness and high light transmission, ensuring that adding protection to your lens does not come at the cost of image quality.

The filter's standout feature is its NiSi SMC (Super Multi Coating) system, which applies 7 layers on one side and 9 layers on the other for a total of 16 anti-reflective coatings. This extensive coating stack significantly reduces ghosting and lens flare when shooting into or near bright light sources. The aircraft-grade aluminum frame keeps the filter lightweight and resistant to impacts, while its precision threading allows smooth attachment and reliable stacking with other screw-in filters such as polarizers or ND filters. For photographers who want an everyday protective filter that genuinely contributes to image quality rather than simply sitting passively on the lens, the NiSi UV395 SMC is a strong choice in the 49mm size.
